LOOSE-LEAF BINDER.

Application filedOctober 1c, 1922. Serial No. 594,900..

To all whom it may concern I Be it known that I, EARLE G. ALDEN, a citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have inventedcertain new and useful Improvements in Loose- Leaf Binders, of whichthe following is a specification. a

This invention relates to loose leaf bind: ers of the type arranged for therapid re ,moval and replacement of large sheets and has for its principal object the provision of a device of this character in which the sheets may be quickly and easily removed and which is capable of expansion to accommo date varying amounts of sheets.

. Another object of the invention is to provide a simple and efficient lock whereby the binding loops can be readilylocked in either the opener closed positions or any other desired intermediate positions.

A furtherobject of the invention is to provide a device of this character in which the sheets will lie perfectly flat in both the open and closed positions,'thereby aflording a perfect writing surface and exposing the full length of the sheet to view.

Other objects and advantages reside in the detailed construction of the invention, which result in simplicity, economy and efiiciency, and which will become more apparent from the followin description.

In the following detailed description of the invention reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description. I

In the drawing I Fig. lie a longitudinal vertical section through the invention, taken on the line 1-1, Fig. '2.

Fig. 2 is a plan view of the binding portion of the invention, partially in section, said section being taken on the l1ne 22,

Fi 1. v i

Fig. 3 is avertical cross section taken on Fig. 5 is a side elevation of a portion of.

the. binder showing the leaves in the open position. This view shows the method of opening the cover.

Fig. 6 .is a fragmentary view of the cover, showing the slots employed therein, to allow the cover to be opened over the binder loops.

Fig. 7 is a detail view of the joint between the fixed and rotatable portions of the binding loops.

Let the numeral 10 designate the base board of the improved binder, consisting of.

cal standards 14. In the drawing, three sets of members 13 and l4,vare shown, but itis understood that as many sets may be em ployed as desired, according to the size of sheets used in the binder.

Vertical standards 14 are securely fixed in sockets 15, formed in the hollow portion 12, ofthe base 10, andterminate in a beveled top, as shown in Fig. 7 The leaves to be used in the binder, designated on the drawing by the numeral 16, are punched with round holes, correspondingin size and spacing to, thevertical standards 14., and placed over said standards/ Standards 13 are each rotatably mounted in a bearing 17, formed in the hollow portion 12 of the base 10, and terminate at their upper extremities in beveled ends which are adapted to fit closely'against the beveled ends of thestandards 14, and form what is practically a continuous rod over which the sheets 16 are turned when the binderis opened.

A cover 18, of stiff binders board or other material, is used to cover the sheets when the binder is closed Cover 18 is provided, near its bound extremity, with a hinge 19,

and a. turned-back portion .20. In the.

turned back portion round holes 21 are placed which fit over the standards 13 and prevent the removal of the cover. Coacting with the holes 21. are slots 22, see Fig. 6, of

sufficient length to fit over the loop 23and enclose both standards 13 and 14. When it is desired to open the cover 18, from the closed position, shown in Fig. 1, to the open position, shown in Fig. 5, the cover is lifted on the standards13 and 14, to the loop 23 and opened as shown in broken lines in "Fig. 5, the slots 22 allowing the loops 23 to pass through the cover; the cover being turned upon the hinge 19.

Fixed to each of the standards 13, within the hollow portion 12 of the base, is a lever arm 24 set at an angle of 45 with the plane of the loop 23. A bar 25 passes throughout the length of the hollow base portion 12 and pivot ally' connects with each of the lever arrns24, as shown at 26, thereby causing all of the standards 13 to rotate in unison when 'anyof themare rotated. One extremity of the bar 25 terminates in an enlarged portion 27, in which is formed a series of transverse slots 28.

Horizontally pivoted over the' portion 27 of the bar 25 is a rocker arm 29, one extremity of which is turned downward so as to engage in'the slots 28; the other extremity of which is pivoted to a vertical shaft 30., which "extends above the base, through a bushing 31, and terminates in a push button 32. Rocker arm 29 is held in engagement with the slots 28 by a leaf spring 33 secured to the base portion 12.

A coil spring 34' is secured to one of the levers 24, and connects with a post 35 in the base. Spring 34 serves to hold the beveled ends of the loops 23, in contact with the beveled endsof the standards 14.

When it is desired to remove or insert a sheet in the'binder, the leaves are opened to the proper place, as shown in Fig. 5; the button 32 is depressed, which in turn releases the arm 29, from the slots in the bar 25, and the loops 23 are turned to position shown in broken lines at 36, Fig. 2; the button is now released and the arm 29 engages in one of the notches 28, thereby locking all of the loops in the open position; the sheet is now inserted or removed as desired, and the button 32 again depressed which releases the arm 29 from the notches 28, and allows the spring 34' to cause the loops to reengage the extremities of the standards 13, and the complete binder is again readyfor use. It will be seen that the loops are always looked in position" so that the danger of disengaging the leaves by dropping the binder or other mistreatment is eliminated.

The hollow portion 12, of the base 10, is secured to the solid portion 11, by means of rivets 37 or in any other suitable manner so that it may be readily removed for repairs.

It "will be noted that the standards 13 are jointed, as shownat 38, Fig. 4, and that the standards 14 are removable. This allows for leather, or other material to match the cover 18, and form a very attractive article.

While I have described and illustrated herein a specific form of my improvement I wish it understood that the samema'y be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is 1. Aloose'leaf binder comprising a base board; a series of vertical standards fixed in said board and adapted to engage the sheets to be bound; a similar series of loopshaped standards pivoted in said board and adapted to engage said first-mentioned standards; levers secured to said loop-shaped standards within said board; a bar pivoted to all of said levers, said bar being provided withslots or notches; a spring'arrange'd to hold said standards in engagement, and means engaging with said notches to hold said loop-shaped standards in any desired position.

2. A loose leaf binder comprising a base board; a series of vertical standards fixed in said board and adapted to engagethe sheets to be bound; a similar series of loopshaped standards pivoted in said board and adapted to engage said first-mentioned standards; levers secured to said loop-shaped arm pivoted to engage in said notches and a push-button shaft extending into the interior of said board and engaging said rocker arm.

3. A loose leaf binder comprising a base board; a series of vertical standards fixed in said board and adapted to engage the sheets to be bound; a similar series of loopshaped standards pivoted insaid board and adapted to engage said first-mentioned standards; levers secured to said loopshaped standards within said board; a bar pivoted to all of said levers, said bar being provided with slots or notches; a spring ar ranged to hold said'standards in engagement; a rocker arm pivoted to engage in said notches; a push-button shaft extending to be bound and: avsimilar series of loopshaped standards pivoted in said board and adapted to engage said first-mentioned 10 standards, said standards being jointed to allow the addition of sections.

In testimony whereof: I aflix my signature.
